%s

Description:

Emitted when a unary operand is used on an object which does not support this type of operation.

Problematic code:

cherries = 10
eaten_cherries = int
cherries = -eaten_cherries  # [invalid-unary-operand-type]

Correct code:

cherries = 10
eaten_cherries = 2
cherries -= eaten_cherries
